Our products

Product category: Extrusion lines for pipes and profiles


● Efficient shield-style screw with a special blending-melt section greatly improves the plasticizing quality and output. and has a wide adaptability of raw material, especially suitable for the efficient extruding of PE/PP/PET/ABS.

● The advanced unsymmetrical notched design; an automatic water cooling system for temperature control is equipped on the feeding section, which duplicates the conveying efficiency.

● The extruder is equipped with sliding guide and a device for adjusting the central height.

● The vertical structure attached with a forced cycling oil cooling system cooled by cycling water. High torque and speed, and low noise; gear with rigid teeth by grinding treatment; heavy duty thrust bearing.

● Driving and temperature control is achieved by PCC control system imported from B&R in Austria, which has been recognized and adopted by many international first-class extruding equipment manufacturers; and a 15″colour touch screen is equipped for easy operation and explicit display.

● Optional innovative MULTIEXTM multi-extruding and feeding system, by means of flexible combination of the extruding system, furtherly optimize the production solution for customized user, so as to realize a perfect matching between pipe sizes and extruder-combination. This solution brings a more flexible production style for you!

1800H Corrugator (making pipes of ID600-1500mm)

● As the core part of the double wall corrugated pipe extrusion line, ZhongyunTechs ZC-1800H corrugator adopts a high efficient water cooling solution for the cooling of mould blocks, which is different from the ordinary gravitational flowing/showering cooling method, can achieve extraordinary cooling efficiency.

● Innovative solution of mould blocks combination technique like building blocks, can easily realize the perfect compatibility of mould blocks between Model 1000 extrusion line and Model 1800 extrusion line. This solution can help you effectively reduce the invest in mould blocks and realize resource sharing! And greatly increase the flexibility of production.

● Innovative mould blocks movement adjusting system can easily realize continuous in-line belling production of corrugated pipes in various lengths so as to greatly facilitates the production of pipes catering to different market demand.

● Innovative multi-extruding and feeding system, by means of flexible combination of the extruding system, can greatly reduce energy consumption of the extrusion line and realize a perfect matching between pipe sizes and extruder-combination . This solution bring a production style of lower cost for you!

1000H Corrugator (making pipes of ID200-800mm)

● Innovative mould blocks cooling solution of Model 1000H corrugator from ZhongyunTech brings a fast and high efficient cooling of mould blocks, substantially increasing the production efficiency of PE double wall corrugated pipes.  
● Innovative design of both the corrugator frame and mould blocks moving structure. When changing the size of mould blocks, you do not need to make any adjustment to the platform or frame of the corrugator any more, so that the work of changing pipe sizes become easier and faster!
● The all-new design of corrugator structure makes the left frame and the right frame which the mould blocks are mounted on be able to open and close freely. 
● The mould blocks on different models of extrusion lines can be interchanged completely through adopting a highly standardized system solution!

● Innovative clasp style rapid assembly technology of mould blocks can realize easy and fast assembly of mould blocks on their bearer plates. This can greatly decrease the workload of changing mould block sizes and substantially increase the work efficiency!
● Based on the further optimized design for the structure and running mechanism of mould blocks, it makes the mould blocks running forward and backward bidirectionally on the corrugator! It effectively overcome the structural defects that ordinary corrugator only allow the mould blocks run in one direction.
